Rebuilding a Fogmaster Tri-Jet 6208

I love well-built, beautiful, strong, dependable machines. I really do. They are “machine sexy,” in my eyes.

One of my favorite and recent acquisitions is a Fogmaster Tri-Ject 6208. Mine was built in the 1960s or early-70s. It still looks great and works well. But, I decided to rebuild it a little just to keep it in tip-top shape.

The Fogmaster Corporation is based in Florida and still makes each of its fogger machines here in the U.S. There’s no reason to not buy a brand new Fogmaster if it’s in your budget. But, if it’s not, you also won’t go wrong with buying an old one at a garage sale or eBay. They’re very dependable.

If you pick up an old Fogmaster and it’s not blowing as strongly as you think it should, it is likely that your hoses are old and in need of replacing. Now, understand that the fine folks at Fogmaster will do this for your free of charge. You just need to pay for shipping and parts. (Seriously! Labor is free!) The hose kit is only $12.50. That’s a heck of a deal.

But if you know me, you know I like to do my own tinkering. So, I decided to cut a few corners and do it myself in my own backyard. If you want to change the hoses in your Fogmaster, trust me, you can do it too.

What you will need:

1 Phillips head screw driver,
about 2 feet of 3/8 inch fuel hose
a sharp knife, and
some brightly colored nail polish.

(Point of note: You see the picture of the nail polish to the left? Notice that it is so important it warrants it’s own picture. Don’t skip the nail polish step. If you use the polish, you will never know the headache it saved you, but if  you skip the step, you will curse yourself later!)

Remove the top part of the Fogmaster from the base (which is the tank). Place the top part of the Fogmaster flat on its nose (the end where the mist is blown). You will see four Phillips head screws.

Loosen the screw, but do not remove them completely. Once they are loosened, you will be able to remove the top part and put it down (see picture).

As you remove the top and the three rings (you will see the flat metal rings as you take it apart), use your brightly colored nail polish to mark where the rings meet each other. When you put it back together, the

ability to line up the colored marks will make this job so much easier.

The picture to the right that shows what it will look under the hood. It’s pretty simple. Your hoses are likely yellow and old. That’s what we are going to replace.

There are five

short hoses. DO NOT REMOVE ALL THE HOSES AT ONCE! You will be asking for trouble if you do.

Remove he small u-shaped hose. Straighten it out next to your uncut fuel hose and cut off a piece the exact same length. Replace that hose.

Continue these steps with each of the five hoses, one at a time.

Continue to remove each tube one at a time, cut the desired about of new tubing, and replace.

You will see that there is a hose that has a three-directional outlet. Replace each tube and be sure to secure them back to this outlet tightly.

When you are finished replacing all five tubes, you will be ready to replace the external tube.

Find the exterior coiled tube. Pull back one end to expose the inner fuel tube. Replace that with fresh tubing.

There is a brass base plate uptake valve. Pull that off to remove and push it back onto the new hose.

And folks, that’s it! It’s very easy to do and if I can do it, I know you can too!

You may be wondering why I didn’t show you a picture of the three rings with the brightly colored nail polish and talk about how easy it was to put this back together. That’s because, it was a beautiful and brilliant afterthought that would have made my morning much more pleasant. You see, I didn’t originally think I was going to write a post

about this, but after I took the Fogmaster apart, I realized it would be a good thing to do. So I turned the various parts this way and that because I recreate the steps and take picture for this post. In doing so, I messed up the alignment and putting it back together

was more of a puzzle than it should have been. I cursed myself the whole time for not having the

forethought to dab a little polish where the pieces lined up so I could put everything back together easier.

  1. Hi Buzz!
    Finally someone has knowledge of the Fogmaster 6208. I purchased one from ebay that was supposed to work. The motor blows super strong, (Almost like an air compressor) but spray only comes from the bottom jet. Other two jets, only air. I took it apart, ran water through all of the lines, switches, splitters, and such, and nothing seems clogged.

    Now that I cannot find any information on what makes the fogger actually work, it sounds like I may have found the woman that can tell me!!! You! :^) Or I hope so.

    Do you have any idea what might be wrong, with this unit? It is only two years old, and I don’t think someone took very good care of it. The tank needed washing out, and I have flushed it out the best that I could.

    I will be so anxious to hear about your Fogmaster adventures. I needed mine to fog barns and areas were wasps have built nests around farm equipment inside the metal tubing. They go inside the small holes an build huge nests, and it is impossible to escape them when you are underneath something laying on your back!!!!

    Thank you ahead of time Buzz. I am going to enjoy reading the rest of your site.

  2. Hi Susan,

    Thanks for your comment. I’ve been so busy around here lately, I haven’t taken the time to write in a while. But your comment will inspire me to get going again!

    Your Fogmaster situation is pretty odd.

    So, you are pretty sure that the tubes are not clogged, but the fogging solution is only coming through one of the “vents” and not the other two?

    I just looked at mine, and I don’t think I can offer any help without completely dismantling mine and putting back together again (which, I’m not too keen on doing because as I recall, putting it back together was as big a pain in the neck as anything :-).

    When you turn it on, do you have the red knob turned to full blast? If you have air coming through it, I think you are in good shape. I suspect something is not connected well or maybe the aluminum openings (what you attached the tubes to) are clogged, but it sounds like you checked all that.

    Have you tried changing the tubing? Tubing from the hardware store is pretty cheap. I think I paid about a dollar or two for gas sized tubing. It’s worth a try. Then fill the reservoir with water and turn it on full blast.

    Let me know if that’s at all helpful. If it isn’t, I’ll scratch my head a little more.
